Series Overview
This series builds on the introductory series to develop a deeper understanding of the core physical mechanisms in spintronics. Starting from the relativistic origin of spin-orbit interaction, we progress through detailed theories of Spin Transfer Torque (STT) and Spin-Orbit Torque (SOT), and explore cutting-edge topics including antiferromagnetic spintronics and skyrmions.
Prerequisites
- Completion of Introduction to Spintronics Series
- Quantum mechanics fundamentals (angular momentum, perturbation theory)

Series Structure
Learn the relativistic origin of spin-orbit interaction (SOI) and understand its manifestations in solids: the Rashba effect and Dresselhaus effect. We explain SOI in heavy metals, semiconductors, and interfaces, and its applications in spintronics.
Study the detailed theory of Spin Transfer Torque (STT) based on the Slonczewski-Berger model. We cover magnetization dynamics under STT, critical currents, and design principles of STT-MRAM.
Learn about Spin-Orbit Torque (SOT) arising from the Spin Hall effect and Rashba effect. We distinguish between field-like and damping-like torques, explain SOT switching mechanisms, and discuss advantages of SOT-MRAM.
Survey cutting-edge topics currently under active research: antiferromagnetic spintronics, magnetic skyrmions, 2D magnetic materials, and topological spintronics.
Connection to Introduction Series
This series is a direct sequel to Introduction to Spintronics. Building on the foundational knowledge of GMR/TMR, spin injection, and Spin Hall effect from the introductory series, we aim for deeper physical understanding and applications to device design.
